Sackorange 608 ZZ Skateboard Bearings, Double Shielded,8x22x7 Miniature Ball Bearings（Pack of 20)

I used this product for a wind spinner and it works better than ever. I also have several spares if needed. It saved my wind spinner from being trashed and I was so happy!

Guys just go to the skate shop. Ik you are looking for a cheaper way to skate, its not worth it. Buy REDZ if you have to but dont do Amazon skate stuff you will regret it. These were very loud, and you didnt get very far skating, but its enough to get you by.

Currently using one as part of a 3D printed stabilizer for my Z-axis on my Ender 3. Its the perfect fit allows rotation and little wobble. Printing has been going a bit faster and cleaner.

This is a very high quality bearing. As others have stated, its got a good thick lubrication applied. Out of the box, they are perfect for heavy loads. For most tinkering and crafting where you want as little friction/resistance as possible, youd probably want to heat these a little and get rid of that lube to install a lighter weight lubrication. Other bearings might spin better out of the box, but the quality will probably be lower. Id recommend these bearings.

I used these bearing to repair some Adult Assistance Walkers, for the elderly people that reside at the Adult Foster Care/Assisted Living facility, where my wife works at. They were going to throw them out, because the wheels were wobbly. She figured that I could probably fix them & save them from going into the dumpster. These fit & worked perfectly! I was happy & pleased with the quality of the bearings, especially for the price. Be sure to check the size bearing that you are going to need for your application or repair. As they do come in very many different sizes. I must add...Shipping was Super Crazy Quick for these too! I was able to repair 3 walkers with this bearing package/kit. I made the Senior Citizens at the facility very Happy! Being able to use Safe, Smooth Rolling Walkers again. I was a Hero in my wifes eyes...even for one day...so, Ill take it!

Clean these bearing out with acetone or similar solvent and they will work pretty good. My uses are under low Load, toys or low rpm applications so I can not comment on high load applications. The 5 star rating is my rating of these performance vs the price. If you are expecting high precision bearing you will need to spend more per bearing.

The bearings are coated with some type of tacky oil (I assume to protect them). The rollers do not turn smoothly and have a lot of resistance. I tried soaking them in Acetone (twice) but had limited success. It did not appear to dissolve all the oil inside the bearing. I tried Xylene and that worked better. I still have 6 bearings with high friction. I will try another soak with Xylene.. If successful I will then lubricate with white oil.

Pretty stiff and sticky out of the tube. A little wd-40 to clean them you and loosen them and they work just fine.

Was swapping these into a 1/5 rc car and out of the 20 I was lucky to get 6 that werent gritty. Well see how long they last but next time Ill spend a bit more and get some from a company that has some better tolerances. After blowing out the grease and re-lubeing they got a bit better but still not as smooth as I am used to. Plus side, they dont chirp but thats about it. Update - 7/31/21 - They chirp. Got gritty quick and not smooth. Look elsewhere.

You’re probably looking at these because they have a good price point, which they do. And that really low price point is the only reason they’re not even more lowly rated. The bearings come heavily coated with grease - enough that it actually hinders rotation. It seems like this is done because it also hides imperfections in the bearings. After clearing the bearings they rotate much more freely, but have a definite wobble to some of them. I compare them to a 20 year old set of real ABEC 7 bearings in my rollerblades and these are definitely not ABEC 7. So, if you’re looking for some bearings for a robotics project where they’re on an idler pulley, these are fine. But if you think you’re gonna drop these into a board or skates, keep looking.
